A Simulation Model of Gypsy Moth-Forest Interaction

$29.50 plus tax (Refund Policy)

Buy Article:


A model developed from data collected in New England simulates the behavior of the gypsy moth (Porthetria dispar (L.))--forest system in many stands and over many years, yielding estimates of future egg mass density, defoliation, tree condition, and tree mortality. It will also yield frequency distributions of expected egg mass density and defoliation levels for one stand in 1 year. This information may be valuable to decision-makers concerned with regulating gypsy moth infestations. Forest Sci. 21:233-238.

Keywords: Porthetria dispar; defoliation; transition matrices

Document Type: Journal Article

Affiliations: Former Principal Ecologist, Northeastern Forest Experiment Station, USDA Forest Service, Upper Darby, Pennsylvania

Publication date: September 1, 1975
